VTo all whom t may .concernn Be it known :that :LLAnoLrH EFRANKEL, a citizen of the United States, and resident of the city of'New York, in the county vof New York and Stateof'New York,have invented certain 'new and usefulImprovementslin chinesfor Attaching Snap Fasteners, of

which" the following is a specication. i

This invention relates to Van improvement "ina machine for attaching snap fasteners Ato gloves, articlesof clothingorthelike, and V`hasforits objecttoprovide a machine of this character which willibe of very simple construction, and which will, by a-simple stroke of a plunger, feedthe snap fasteners to the proper point of attachment to the l glove and secure the same thereto.

A further objectof this invention is to provide a machine` for attaching snap fasteners in which the operation of attaching the male and female `fasteners to the opposite edges of a glove or otherarticleof clothing' is lperformed by a single plungerstroke.

.simple form, so, that'itsimportant details of vconstruction and mode of operation may be readily understood and appreciated.Y

Throughout the various vviews `of ythe drawings, similar reference.characters designate similar parts.

In the embodiment of .my invention, as

fdisclosed herein, I have shown the mainsupjporting `frame of themachine of substantially `rectangular form, `provided with a 'front longitudinal frame member l and a rearlongitudinal frame member 2. VV These members .l and 2 may be of any suitable` length according to the size of the machine desired, and they are connected'a'trtheir ends byjthe cross members 3 and 4. The frame thus provided'may besuppo'rted upon a suitablestandard or a table, as maybe desired. A f o The front member l is divided at a substantially central point ,to .provide a Yspace for the operation of the plunger mechanism, work' clamp and other attendant, mechanism to be hereinafter described. The space just mentioned i-s bounded by transverse cross braces 5 and 6 which act as supports for "slides 7V and-8 forming conveyingV means for l,portions of snap 'fasteners as will be hereinafter described.

At 25 and 26 are hoppers which supply ysuccessive fastener members to thelslides 7 and 8 which carry said fastener memberskto a point below the article, such as a glove or xthe like, to which they are to be attached.

These slides 7 and 8 constitute lower slides which are moved to a point below the vglove or other article, and which carry parts-of one of the snap fastener members.

In Figures k5 and 6 is shown the form-of snap fastener particularly adapted :for use in my improved machine, wherein 1l designates the male or stud member of thefastener and 14 indicates the female orsocket member which receives and interengages yto with the studv member 11 in the usual manner.

lThe male member 11 is attached to an article, aportion of which is indicated at 76, by means of an attaching plate or disk 10 which is provided with a pair of prongs 13 adapted to extend through the fabric 76 and interengage or interlock with a flange 12 eX- tending about the edge of the studl member 11. y

In Figure 6 is shown the female or socket member of the snap fastener and the .manner in which it is'attached to an article, the article being indicated as at 75. rI`he female member is shown at 14 and is provided with a pair of prongs 15 which arer forced through the fabric 75 and interengage or linterlock with a circumferential ange 17 whichfis rolled or curled on the edge of a cup-shaped cover disk 16. It will be seen from the foregoing that t-he construction of the fastener members is such that they may be readily attached to the opposite edges of a glove, article of clothing or the like by pressure together of the respective parts such as can be done by a simple plunger movement.

Mounted to slide uponr the upper face of the front member 1 of the frame, is a pair of slides 18 and 19 which act to receive successivefastener members from the hoppers 23 and 24. As each fastener'member consists of two parts orv elements, two of the slides co-operate to supply the parts or elements for each fastener member. Thus, the slide 8 supplies the cover disks 16 and the slide v18 supplies the female members 14.

A hopper 26 contains a plurality of stacks of Ydisks 16 and supplies said disks one at a time to the slide 8 where said disks are received in a recess '32 provided for them, while the hopper 23, whichis mounted over the slide 18, supplies successive female fastener members 14 to the slide 18 where they are received in an aperture 21 in said slide. The two slides 8and 18 thus act4 to carry both parts of the female memberfto a position above and below the article to which they are vto be attached and plunger mechanism acts to unite the parts 14fand 16 together and to attach said parts in (their united state tothe article. y

In similar manner the slides 7 and 19 cooperate to supply the parts for the male or stud membei` of the snap fastener. A hopper 24 supplies the attaching plates 10 one at a time to theslide 19 where they are successively receivedv in Lan aperture 2O in'said slide and a hopper 25 supplies stud members 11 one at a4 time to the slide 7 where they are successivelyreceived in a recess 33 provided in said slide 7 for their reception.

Each ofthe hoppers 23, 24, 25 and 26 is mounted upon an upright square bar 27 and said bars` project downward through the frame and are mounted so as to be free to rotate therein. Mechanism is provided to enable the hoppers to be shifted about their vertical axes as will be hereinafter explained.

To permit the four slides to freely reciprocate without interference by the hoppers, each slide is provided with a central longitudinal slot through which the vertical bar or rod 27 on eachhopper may project. In the slide 8 the slot just mentioned is disclosed at 31; inthe slide 7 at 34; in the slide 18 at 29; andin the slide 19, at 30.

At 35 and 36 is disclosed a pair of supporting plates which act to support the opposite edges of the glove during the operation of securing the fastener members to it. These plates 35 and 36 arev located a slight distance below the under face of the slides 18 and 19'so that when the glove is resting upon the plates 35 and 36 it will not project y upward in such a manner as to interfere with the movement of the slides 18 and 19. A space, indicated atk 68 is also provided below these plates so that the slides 7 and 8 may freely move to a position below them.

The plate 35 is provided with a Central opening or aperture 37 and the plate 36 is provided with asimilar aperture 38. The slide 8 is provided with a recess 32 which receives a cover disk 16 and moves it forward to aposition below the aperturer 37 in the plate 35, while the slide 18 simultaneously receives a its aperture 22 and a position over the plate 35, and comes to rest directly Vover and in alignment with the aperture 37 in socket member 14 in moves 1t forward to ysaid plate 35.v Similarly, ythe slide 7 receives a stud fastener member 11 in its recess and moves it forward' to a position directly lbelow the aperture 38 in the plate 36, while the slide 19 receives an attaching plate 10 in its aperture 20 and moves the same over the top of the glove, whose opposite edge is resting on the plate 36, and comes to rest in direct registration or alignment with the aperture 38 in said plate. The parts in this position are shown in Figures 2 and 7.

Each of the hoppers is provided with four channels or grooves 28 in which stacks of their respective parts are contained, and the groove located nearest to the slide opening or recess is the groove which supplies the fastener parts to its slide. Vhen the supply of parts in the groove 28 which is located nearest to the slide opening is exhausted,

the. hopper is simply rotated about its vertical axis until one of the other grooves full .with parts is positioned nearest 'to the slide glove resting on the of the bars 27 upon which thefhoppers are carried.

The hopperrotatingv frame ust described may be mounted in any way so as-to slide on the machine to rotate the hoppers when necessary and it; may be supported in any desired manner on the frame of the mai chine, as bythe brackets 72 -which permit it tov have its ldesired sliding movement. A

handle portion 73l is provided at one end 'of the hopper-,shifting frame to permit the sam-e to .be readily shifted manually.

- For the purpose of `holding the` glove down; securely upon its supports 35 and 36l while the operation of attaching the fastener members to the same takes place, I provide a clamp consisting of a frame 41 having its opposite ends resting upon the plates v and 36 and pivoted at42. This clamp and attendant mechanism is clearly shown in Figures 1, 8 and- 9, the same being omitted from Figure 4 for the purpose ofk avoiding complexity in that particular View:

One end of the clamping frame 41 extends under the upper end of a plate 39 which is pivoted to the frame members 5 and- 6-as at 40. Theends of the clamping frame which rest upon the plates 35 and'36 being preferably Weighted they normally bear downward upon said plates and securely hold thereon the opposite edgesl of the glove thrust under them. lVhen the operation of attaching the fasteners to the glove has taken place and it is desired to= release the glove from the pressure of the clamp`41, thisis done4 by pressing inwardly on a sliding arm 43 which extends through the frame member 1 and said arm is caused to exert pressure against the lower end of the plate 39 below its pivot 40, causing said plate to bear downwardly upon `the end of the clamping frame which extends or projects beneath its upper end, with the result that said clamping frame is movedabout its pivot 42land its ends` are lifted so. that the edges of the glove are freed and the glove may be removed.

The clamping mechanism just mentioned provides a means for holding down the opposite edges of the Vglove'while the snap fastener members are being attached, .and

as a further means 'for holding the glove taut on its supports, I provide a linger 45 under which the centra-l part of the wrist portion. of the glove is held during the snap fastener aiiixing operation'. This linger is preferably Vformed vas part of, or secured to a bar-44 which extends -between and connects the `frame members fand 6.`

Pivoted at 46 tothe end of the slide 13 is a link 47, which `has its upper end pivoted at 48 toa frame 49. Similarly, thek slide 19 is pivoted at 50 to a link lwhich has its end pivoted at 52 to the opposite side member of the frame 49. The side members sie of the frame extend `diagonally:rearward wherexone of them` is pivoted at'55 to a link 54 having yits lowerend; pivoted at 53 to the end or" the slide'8.y The-other sidelmem= ber-of the frame 49 has itsrear' end pivoted at 58V to* a linl' 57 which has its lower end pivoted at 56 to the end. ofY the slide 7.` I-t will bexseeni from the foregoing that as the side members of the frame 49A are connected together by au cross! member 59,. the four slidesV 7,8,y 18 andv 1-9 are connected toa single frame so that when said frame is lowered the. slides are caused, by :reason of' their link connectiont-o the frame, tovslide towards theV supporting plates 35 and 36, and whenv the frame y49 is raisedl the slides are caused to move away from the. plates 35 and. 36 backward to the hoppers to receive 'snap fastener parts therefrom.

At 60is shown aplunger which is adapted to bev vertically re'ciprocated in a boss 63. formed in the frame of the machine. This plunger 60 is provided with a portion'64 n extending downward below the frame of the machine, andl said portion 64 is provided: at its lower end with a foot-engaging plate 65. At itsA upper end the plunger is provided with a horizontally extending portion 62 which projects forward towards the front of the machine. At the front end of this horizontally extending portion 62 of the plunger, I providea plunger member 66 having a pairiof downwardly projecting punch members 67 and. 69 which extend downward directly over and in line `wit-h the apertures 37 and 38 in the Vplates 35y and 36.

A spring-61 connects thep-lunger 60 to the cross member 59 of the slide-reciprocatlng frame 49 so that when said plunger is raised it will, through the medium of said spring 6l, raise the frame 49 so that the four slides 7, 8, 18 and 19 will be drawn back so that their apertures will move into position below the respective hoppersV to receive parts therefrom.

From the foregoing the operation of my improved machine will be readily understood. In the drawings, the slides are shown in a mid-way position. The normal position of the machine is attained when the plunger 60 has beencraised tov such an extent to: cause the frame 49 to be raised so that it draws the slides 7, 8, 18 and 19 towards the hoppers and positions them with their respective apertures 20, 21, 32 and 33 under their respective hoppers. Through gravityV a fastener member is forced into each aperture in4 eachslide, the aperture 2() in the slide 19 receiving a plate 10; the aperture or recess 33 in the slide 7 receiving a stud member 11; the aperture 21 in the slide` 18 receives a socket member 14 and the recess 32 in the slide- .8 receives a cover disk 16.

Pressure on the plate'43 raises the ends opposite edges of the glove with their aper-v tures 2O and 2li in idirect' alignment with the apertures 37: and 38 respectively in the support-ing plates 35 and 36. Simultaneously with this the slides 7 and 8 are brought to rest below the plates 36 and 35- respectively, the parts at this time being in the position disclosed in Figures 2 and v7.

As further downward.'movement ofthe plunger continues its pun'chmembers 67 and 69 pass through 4the respective slide apertures 21 and 2O `forcing therespective snap fastener members downward through saidy apertures andr causing their prongs 13 andV 15' toI pierce vthrough the glove. and interlock with the ianges 12 and 17. The plunger 'is then permitted to ascend, such ascension drawing back the slides to their positions below their respective hoppers where theyreceive the next snapfastener parts in readiness for the next glove. To enableA av snap yfastener member lto be supported within the slide apertures 20 and 21 Iprovide the interiorof eachv of these Aapertureswith a pair of springs 22 which act to supportJ the members in the openings until the members are forced pastsaidl springs by the punch members ,67 and 69 on the plunger'. f i

When the supply of fastener members in the groove 28 Aof the hoppers, located near# est to the slide openings is exhausted the hoppers are shifted by movement of the rack untilV a filled groove in veach hopper is located nearest to the slide openings. v

The fastener members are so placed in the various `hoppers that they apply the snap fasteners in such 'a manner as is required on 'a glove used on the right hand. When the fasteners'are to be applied to a glove used on lthe left f hand their positions are reversed, thatis, the stud fastener members 11 a'rejused inthe hopper 26 vand the attaching plates l() are carried in the hopper`23. The socket fastener members are under such circumstances carried in the hopper 24 and the disks 16 for such socket members are carried in the hopper 25. y
